Renesas Electronics announced that it will introduce an updated version of its "Embedded Target for RH850 Multicore" model-based development environment for its multi-core automotive control microcontrollers (MCUs). This updated version supports the development of a multirate control (multi-control cycle) system, which is currently a common technology in systems such as engine and body control. Even for software development of multi-core MCUs, this modeled development environment can become practical, especially in the development of driverless vehicle control systems.

The RH850 multi-core model development environment previously introduced by Renesas can automatically allocate software to multiple cores. Although it is possible to verify its performance, it must be manually operated in complex systems that include multi-rate control. Ways to accomplish everything including RTOS and device drivers. Now, in response to the ever-increasing performance requirements of engines and automobiles, as well as shortening product development time, multi-rate control is directly implemented by allowing this development environment to support multi-rate control models. In this way, simulation performance can be used to evaluate execution performance.

As a result, it is not only make it possible to evaluate execution performance during the initial stages of software development, but it is also easy to feed back validation results to the model itself. This allows the integrity of the system development to be improved in the early stages of the development process, and the burden on the increasingly large and increasingly complex software systems for development can be greatly reduced. Renesas is accelerating the practicality of the modeled development environment in the development of multi-core processor software and leading the development of the green electric vehicle proposed in the concept of “Renesas autonomy”.

This updated model development environment is expected to support dual-core Renesas RH850/P1H-C MCUs in the fall of 2018, and plans to support up to six core RH850/E2x series MCUs in the future. In addition, Renesas also plans to deploy this development environment to the entire Renesas Autonomy platform including the "R-Car" series of SoCs.

In the fall of 2018, Renesas will begin to provide an updated version of the modeled development environment "Embedded Target for RH850 Multicore," which will be displayed at the MathWorks Automotive Conference 2018 event on July 3, 2018 at the Shinagawa Convention Center in Tokyo.
